'imprecisely-returned' originates from the combination of 'imprecisely' and 'returned', where 'imprecisely' is derived from Latin 'im-' meaning 'not' and 'precisus' meaning 'cut off, brief', and 'returned' from Old French 'retourner', meaning 'to turn back'.

'imprecisely' evolved from the Latin 'imprecisus', and 'returned' from the Old French 'retourner', eventually forming the modern English term 'imprecisely-returned'.

Initially, 'imprecisely' meant 'not precise', and 'returned' meant 'to go back', evolving into the current meaning of 'returned in an imprecise manner'.
